Although progressive right ventricular (RV) enlargement (RVE) is common in patients with pulmonary regurgitation after tetralogy of Fallot (TOF) repair, the rate RVE and progression RV dysfunction varies among patients. The present study aimed to investigate independent predictors rapid repair TOF, using serial cardiac magnetic resonance imaging (MRI).The included consecutive who underwent MRI more than twice between January 2005 March 2015 TOF. Patients surgical valve implantation or any...
Over the last decade, extracorporeal membrane oxygenation (ECMO) use in critically ill children has increased and is associated with favorable outcomes. Our study aims to evaluate current status of pediatric ECMO Korea, a specific focus on its volume changes survival rates based diagnostic indications.
Chylothorax after congenital heart surgery is not an uncommon complication, and it associated with significant morbidity. However, consensus treatment guidelines are lacking. To improve the outcomes of patients postoperative chylothorax, we implemented a standardized management protocol at Severance Hospital in September 2014.A retrospective review treated single center was done. All corrective palliative operations for disease performed our institution between January 2008 April 2018 were...
Cardiac surgery with cardiopulmonary bypass (CPB) is a known risk factor for acute respiratory distress syndrome (ARDS). We aimed to analyze the treatment outcome in patients who required veno-venous extracorporeal membrane oxygenation (VV-ECMO) postcardiotomy ARDS despite other rescue modalities.We retrospectively reviewed outcomes 13 (mean age, 54.7±5.9 years) received VV-ECMO support refractory after cardiac between March 2013 and February 2016 at Severance Hospital, Yonsei University...
The clinical outcome of children with severe acute myocarditis who require mechanical circulatory support is not well known. Therefore, we studied the survival and courses patients fulminant supported by extracorporeal life (ECLS).We performed a retrospective chart review 13 consecutive were treated ECLS between April 2013 2015. Demographics, initial symptoms, laboratory results, management, last follow-up status investigated.The median age was 25.8 months (range, 2.9 to 11.5 years) body...
BACKGROUND:Rotational thromboelastometry (ROTEM®) is a point-of-care test for coagulation, enabling physicians to make swift decision. The aim of this investigation was establish reference intervals thromboelastometric evaluation coagulation in pediatric patients with congenital heart diseases (CHD). MATERIAL AND METHODS:As baseline data, 3 assays ROTEM® (INTEM, EXTEM, and FIBTEM) were measured after anesthesia induction. parameters clotting time (CT), amplitude at 10 min (A10), clot...
Patients with venoarterial extracorporeal membrane oxygenation (ECMO) frequently suffer from pulmonary edema due to left ventricular dysfunction that accompanies heart dilatation, which is caused by atrial hypertension. The problem can be resolved atrium (LA) decompression. We performed a successful percutaneous LA decompression an septostomy and placement of venting cannula in 38-month-old child treated ECMO for acute myocarditis.
A 42-year-old woman with short-term memory loss visited Gangnam Severance Hospital, and her chest X-ray computed tomography revealed a right anterior mediastinal mass. On hospital day two, she suddenly presented personality changes drowsy mental status, so required ventilator care in the intensive unit. She underwent thymectomy, was pathologically diagnosed thymoma, type B1. Her status eventually recovered by postoperative 90. Paraneoplastic encephalopathy associated thymoma is very rare,...
Redo coronary artery bypass grafting (CABG) is still associated with increased morbidity and mortality as compared to the first-time operation. Further, application of off-pump technique redo CABG limited due technical difficulties. The aim this retrospective study was analyze early midterm results after compare outcome on-pump CABG.From June 1996 October 2011, elective performed in 32 patients. Mean age 64.8 years (on pump 64.3 vs. off 65.5 years; p=0.658), 21 patients were male. Among...

Functional tricuspid regurgitation (TR) usually decreases after atrial septal defect (ASD) closure; however, it may persist and cause heart failure that requires treatment. We aimed to investigate clinical echocardiographic factors predicting persistent TR ASD closure.Among 348 adults who underwent isolated closure between January 2010 September 2020, 91 (26.1%) patients with significant (at least moderate degree) before were included. Persistent was defined as on echocardiography at 6...
Objective: To evaluate flow pattern characteristics in the ascending aorta (AA) with four-dimensional (4D)-flow MRI and to determine predictors of aortic dilatation late after tetralogy Fallot (TOF) repair. Materials Methods:This study included 44 patients repaired TOF (25 males 19 females; mean age, 28.9 ± 8.4 years) 11 volunteers (10 1 female, 33.7 8.8 who had undergone 4D-flow MRI.The diameters, velocity, wall shear stress (WSS), jet angle (FJA), displacement (FD) at level sinotubular...
A 4-month-old boy diagnosed with acute myocarditis was treated extracorporeal membrane oxygenation (ECMO). Follow-up echocardiography eight hours after ECMO revealed intracardiac thrombosis involving all four heart chambers. Because of the high risk systemic embolization due to a pedunculated thrombus aortic valve, we performed an emergency thrombectomy. After operation, patient had minor neurologic sequela left upper arm hypertonia, which almost disappeared at last outpatient clinic two...
We retrospectively evaluated the association between preoperative mild thyroid dysfunction (subclinical hypothyroidism [SCH] or low triiodothyronine [T3] syndrome) and outcomes in patients who underwent off-pump coronary surgery (OPCAB). Further, 800 (2015−2020) were divided into euthyroid, T3, SCH groups. The primary outcome assessed with composite endpoints (myocardial infarction, prolonged mechanical ventilation [>24 h], acute kidney injury, 30-day/in-hospital mortality). secondary...
A two-month-old infant presented with coarctation of the aorta, severe left ventricular dysfunction, and moderate to mitral regurgitation. Through median sternotomy, aortic arch was repaired under cardiopulmonary bypass regional cerebral perfusion. The patient postoperatively supported a assist device for five days. Left function gradually improved, eventually recovering concomitant regression Prompt surgical repair aorta is indicated patients dysfunction. central approach back-up safe...
The management of recurrent tricuspid regurgitation after valve repair in patients with Ebstein anomaly is difficult, and replacement most commonly performed such patients. We report two cases that were successfully re-repaired using the cone technique. technique a useful surgical method for reconstructing competent valve, can be applied who have undergone previous repair.
Matching for the rhesus (Rh) blood group is currently not taken into account in organ allocation system. However, Rh-mismatched transplantation, primary concern potential RhD-negative recipients to develop sensitization and produce anti-D anti-bodies if they receive a transfusion of RhD-positive blood. It estimated that over 80% may experience Rh allosensitization when exposed blood, although this occurrence less common solid organs. In theory, who organs from donors are at risk...
A 3-year-old boy with Glenn physiology exhibited refractory heart failure reduced ejection fraction.To improve the patient's oxygen saturation, he underwent ventricular assist device (VAD) implantation concomitant Fontan completion.The extracardiac conduit operation was performed a 4-mm fenestration.For VAD implantation, Berlin Heart cannulas were positioned at left apex and neo-aorta.Following weaning from cardiopulmonary bypass, temporary continuous-flow VAD, equipped an oxygenator,...
A 7-month-old girl with no medical history was treated mechanical circulatory support due to myocarditis.Her cardiac contractility did not improve despite more than one week of extracorporeal membrane oxygenation treatment.Thus, we planned a heart transplant.However, high level cytomegalovirus found in blood laboratory results by quantitative polymerase chain reaction.The patient's recovered normal range four days after ganciclovir treatment.She discharged slightly decreased left ventricular...
